the upgrade is manual via ftp. First download the latest version to your PC
Unzip the download file, and just go inside
then you will find the landera folder:
go inside folder landera, you will find many files that you have to upload via ftp
On your hosting, find the plugin folder (wordpress root dir)/wp-content/plugins/landera-pro/. then upload via ftp all the files from uncompressed folder landera to your remote folder (that you found on previous) on your hosting.
After replacing, you will have the latest version.
